Overdose - Extremely Adverse Effects

[ovadose]

SWIM has taken adderall twice before this incident. The only pills available to SWIM are 30 mg Adderall XR.

The previous experiences, SWIM only took a single 30 mg dose each time. However, yesterday SWIM really needed to get alot of school work done, so he started by taking 1 30mg xr. Then about 4 hours later, he decided to take another. And then at midnight he took yet another. During that night, SWIM didn't really experience any adverse effects other than an inability to get to sleep.

However, when morning came around, SWIM found himself almost fainting every time he stood up. His heart was beating rapidly, and he was experience heart palpatations as well. Despite this, SWIM went to school and only felt a little sick. At about noon, though, SWIM started to experience the rapid pulse/palpatations and started hallucinating as well. Everything was moving and squiggling around like on a low dose of acid, and SWIM was also experiencing some odd thoughts. These lasted until about 2. Then SWIM was hit by some incredible naseua.

As of now, SWIM still feels very naseous and still has not returned to a normal heartbeat (although it is getting much better).

Why the incredibly aweful effects, and why are they still affecting me the day after? Did I overdose? Help please!
